'Letter' in the Bible

Therefore, the king of Aram said, “Go and I will send a letter with you to the king of Israel.”So he went and took with him 750 pounds of silver, 150 pounds of gold, and 10 changes of clothes.

He brought the letter to the king of Israel, and it read:When this letter comes to you, note that I have sent you my servant Naaman for you to cure him of his skin disease.

When the king of Israel read the letter, he tore his clothes and asked, “Am I God, killing and giving life that this man expects me to cure a man of his skin disease? Think it over and you will see that he is only picking a fight with me.”

When this letter arrives, since your master’s sons are with you and you have chariots, horses, a fortified city, and weaponry,

Then Jehu wrote them a second letter, saying: If you are on my side, and if you will obey me, bring me the heads of your master’s sons at this time tomorrow at Jezreel. All 70 of the king’s sons were being cared for by the city’s prominent men.

When the letter came to them, they took the king’s sons and slaughtered all 70, put their heads in baskets, and sent them to Jehu at Jezreel.

Hezekiah took the letter from the hand of the messengers, read it, then went up to the Lord’s temple, and spread it out before the Lord.
